In very late August 2009, after tying him to the club for four more years, Depor agreed to loan Bergantiños once again to the Andalusians, in another season-long move.[2] He made his La Liga debut on 30 August, playing the last 30 minutes in a 2–0 away loss against RCD Mallorca,[3] and produced roughly the same numbers than in the previous year as the Andalusians were immediately relegated.[4][1]
Bergantiños returned to Galicia in 2011–12, and soon became a regular, appearing in all the league games and helping his team achieve promotion back to the top flight.[7] He scored his first goal in the competition on 20 October 2012, but in a 5–4 home defeat to FC Barcelona.[8] Weeks later, he extended his contract until 2016, with a buyout clause of €10 million.[9]
In September 2015, Bergantiños signed a new deal lasting until 2018.[10] On 12 December that year, against Barcelona again but at the Camp Nou, he helped the visitors come from behind 2–0 to draw it 2–2 by netting in the 85th minute.[11]
On 2 March 2017, in his first league game of the season, Bergantiños had an accidental collision with Fernando Torres, from which the Atlético Madrid striker suffered cranial injuries; he visited the opponent in hospital shortly afterwards.[12] Ten days later, he scored the winner in a 2–1 victory over reigning champions Barcelona at the Estadio Riazor.[13]
On 11 July 2017, shortly after committing himself to another year at Deportivo,[14] Bergantiños was loaned to Sporting de Gijón for one year.[15] Upon returning home, he became the captain.[16]
Bergantiños remained at Deportivo following their historic relegation to Segunda División B in 2020. The 35-year-old skipper signed a new deal on 5 October that year, to last until 2022.[17]
